Frederic Lardinois:

Twitter just announced that it will soon update its terms of service for developers and prohibit third-party advertising networks and developers from inserting ads into a user’s stream. This could mean the end of a number of third-party advertising networks like and 140 Proof, both of which created their businesses around in-stream ads. According to Twitter’s COO, Dick Costolo, the company decided to take this step in order to “preserve the unique user experience Twitter has created” and ensure the “long-term health and value of the platform.”

This is going to cause a lot of trouble for free Twitter apps that make their money this way (especially with the free and excellent Twitter for iPhone that was just released).
